Abstract
A color display system comprises a radiation generator in which the intensity of at least four wavelength bands can be controlled to reproduce a desired color. The system includes an intensity modulator that generates a multiplicity of modulation control signals each corresponding to a respectively different one of the wavelength bands. A multi-wavelength radiation source provides a plurality of narrow-band radiation signals, each corresponding to a respectively different one of the wavelength bands. The radiation source is responsive to the control signals to control the intensity of each of the narrow-band radiation signals to provide a plurality of modulated narrow-band radiation signals. The plurality of narrow-band radiation signals are combined to reproduce the desired color.
